passt: Relicense to GPL 2.0, or any later version In practical terms, passt doesn't benefit from the additional protection offered by the AGPL over the GPL, because it's not suitable to be executed over a computer network. Further, restricting the distribution under the version 3 of the GPL wouldn't provide any practical advantage either, as long as the passt codebase is concerned, and might cause unnecessary compatibility dilemmas. Change licensing terms to the GNU General Public License Version 2, or any later version, with written permission from all current and past contributors, namely: myself, David Gibson, Laine Stump, Andrea Bolognani, Paul Holzinger, Richard W.M. Jones, Chris Kuhn, Florian Weimer, Giuseppe Scrivano, Stefan Hajnoczi, and Vasiliy Ulyanov. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>

test: Speed up by cutting on eye candy and performance test duration We have a number of delays when we switch to new layouts that were added to make the tests visually easier to follow, together with blinking status bars. Shorten the delays and avoid blinking the status bar if $FAST is set to 1 (no demo mode). Shorten delays in busy loops to 10ms, instead of 100ms, and skip the one-second fixed delay when we wait for the status of a command. Cut the duration of throughput and latency tests to one second, down from ten. Somewhat surprisingly, the results we get are rather consistent, and not significantly different from what we'd get with 10 seconds. This, together with Podman's commit 20f3e8909e3a ("test/system: pasta_test_do add explicit port check"), cuts the time needed on my setup for full test run from approximately 37 minutes to...: $ time ./run [exited] PASS: 165, FAIL: 0 Log at /home/sbrivio/passt/test/test_logs/test.log real 15m34.253s user 0m0.011s sys 0m0.011s Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Tested-by: David Gibson <david@gibson.dropbear.id.au>

set TIME 1
test/perf: Simplify calculation of "omit" time for TCP throughput For the TCP throughput tests, we use iperf3's -O "omit" option which ignores results for the given time at the beginning of the test. Currently we calculate this as 1/6th of the test measurement time. The purpose of -O, however, is to skip over the TCP slow start period, which in no way depends on the overall length of the test. The slow start time is roughly speaking log_2 ( max_window_size / MSS ) * round_trip_time These factors all vary between tests and machines we're running on, but we can estimate some reasonable bounds for them: * The maximum window size is bounded by the buffer sizes at each end, which shouldn't exceed 16MiB * The mss varies with the MTU we use, but the smallest we use in tests is ~256 bytes * Round trip time will vary with the system, but with these essentially local transfers it will typically be well under 1ms (on my laptop it is closer to 0.03ms) That gives a worst case slow start time of about 16ms. Setting an omit time of 0.1s uniformly is therefore more than enough, and substantially smaller than what we calculate now for the default case (10s / 6 ~= 1.7s). This reduces total time for the standard benchmark run by around 30s. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Stefano Brivio <sbrivio@redhat.com>

test/perf: Start iperf3 server less often Currently we start both the iperf3 server(s) and client(s) afresh each time we want to make a bandwidth measurement. That's not really necessary as usually a whole batch of bandwidth measurements can use the same server. Split up the iperf3 directive into 3 directives: iperf3s to start the server, iperf3 to make a measurement and iperf3k to kill the server, so that we can start the server less often. This - and more importantly, the reduced number of waits for the server to be ready - reduces runtime of the performance tests on my laptop by about 4m (out of ~28minutes). For now we still restart the server between IPv4 and IPv6 tests. That's because in some cases the latency measurements we make in between use the same ports.

test/perf: Start iperf3 server less often Currently we start both the iperf3 server(s) and client(s) afresh each time we want to make a bandwidth measurement. That's not really necessary as usually a whole batch of bandwidth measurements can use the same server. Split up the iperf3 directive into 3 directives: iperf3s to start the server, iperf3 to make a measurement and iperf3k to kill the server, so that we can start the server less often. This - and more importantly, the reduced number of waits for the server to be ready - reduces runtime of the performance tests on my laptop by about 4m (out of ~28minutes). For now we still restart the server between IPv4 and IPv6 tests. That's because in some cases the latency measurements we make in between use the same ports.

test/perf: "MTU" changes in passt_tcp host to guest aren't useful The TCP packet size used on the passt L2 link (qemu socket) makes a huge difference to passt/pasta throughput; many of passt's overheads (chiefly syscalls) are per-packet. That packet size is largely determined by the MTU on the L2 link, so we benchmark for a number of different MTUs. That works well for the guest to host transfers. For the host to guest transfers, we purport to test for different MTUs, but we're not actually adjusting anything interesting. The host to guest transfers adjust the MTU on the "host's" (actually ns) loopback interface. However, that only affects the packet size for the socket going to passt, not the packet size for the L2 link that passt manages - passt can and will repack the stream into packets of its own size. Since the depacketization on that socket is handled by the kernel it doesn't have a lot of bearing on passt's performance. We can't fix this by changing the L2 link MTU from the guest side (as we do for guest to host), because that would only change the guest's view of the MTU, passt would still think it has the large MTU. We could test this by using the --mtu option to passt, but that would require restarting passt for each run, which is awkward in the current setup. So, for now, drop all the "small MTU" tests for host to guest. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
